Example 2

With continued reference to FIG. 1 , correspondingly, an embodiment of the present application further provides an adjustable strap, including: a first housing 60, a second housing 61, a strap 62, and an adjustment mechanism as in Embodiment 1.

The first housing 60 is coupled to the second housing 61 and surrounds the mounting cavity. In the mounting cavity, the limiting unit 10 is coupled to the first housing 60. Specifically, referring to FIG. 2, the limiting unit 10 is fixedly coupled to the first housing 60 through the connecting portion 11, and the connecting portion 11 cannot be moved or rotated relative to the first housing 60.

Both ends of the strap 62 extend into the mounting cavity. Specifically, the second housing 61 is provided with an extension inlet, and the extension inlet communicates with the mounting cavity, and both ends of the strap 62 enter the mounting cavity through the extension inlet. The second housing 61 is provided with an adjustment hole 63 that communicates with the mounting cavity, and the adjustment unit 20 is connected to both ends of the strap 62 through the adjustment hole 63. Specifically, the adjusting unit 20 is connected to the two ends of the strap 62 through the transmission portion 21, and the transmission portion 21 enters the mounting cavity through the adjusting hole 63. Both ends of the strap 62 extend into the mounting cavity and are connected with the transmission portion 21, and operate. The wheel 211 is blocked by the adjustment hole 63 outside the mounting cavity.

The control unit 30 is disposed outside the mounting cavity and is connected to the limiting unit 10. When the limiting unit 10 is separated from the adjusting unit 20, the locking teeth 13 are separated from the locking teeth 23, and the adjusting unit 20 is rotated bidirectionally to tighten or loosen the strap 62. When the limiting unit 10 is connected to the adjusting unit 20 When the locking teeth 13 are engaged with the locking teeth 23, the limiting unit 10 limits the one-way rotation of the adjusting unit 20 to Tighten the strap 62.

For the manner in which the strap 62 is coupled to the transmission portion 21, an achievable manner is that the strap 62 is fixedly coupled to the transmission portion 21. Specifically, after the two ends of the strap 62 extend into the mounting cavity, the two ends of the strap 62 are fixedly connected to the transmission portion 21. When the transmission portion 21 is rotated, the strap 62 may be wrapped around the transmission portion 21 or unwound. The state allows the strap 62 to be tightened or relaxed.

Another achievable manner is that, when referring to FIG. 1 , when the transmission portion 21 includes the transmission gear 212 , the ends of the strap 62 are provided with racks 621 . The two racks 621 are respectively meshed and coupled to opposite sides of the transmission gear 212, and when the transmission gear 212 rotates, the two racks 621 are moved in opposite directions. Specifically, when the two racks 621 are moved toward the extension of the opponent, the strap 62 is tightened and adjusted, and when the two racks 621 are moved away from the entrance of the opponent, the strap 62 is relaxed. Adjustment. In addition, it is also possible to achieve the tightening or relaxation of the strap 62 by applying a compressive force or a tensile force to the rack 621.

It should be noted that, in the manner in which the two types of straps 62 are connected to the transmission portion 21, when the strap 62 is loosely adjusted, it is necessary to separate the adjustment unit 20 from the limiting unit 10 by the control unit 30. When the strap 62 is tightened, whether the adjustment unit 20 is separated from the limit unit 10 can complete the tightening adjustment.

When the tightening or loosening of the adjusting strap 62 is performed, it can be completed by rotating the adjusting unit 20. Since the transmission portion 21 passes through the adjusting hole 63 and enters the mounting cavity and is connected with the strap 62, the operating wheel 211 is blocked by the adjusting hole 63. Outside the chamber, the adjustment unit 20 thus rubs against the second housing 61 when it is rotated, and the use for a long time inevitably causes damage. Referring to FIG. 1 and FIG. 5 , in order to reduce the damage caused by the friction between the adjusting unit 20 and the second housing 61 , in the embodiment of the present application, the sealing ring 64 is disposed between the adjusting unit 20 and the second housing 61 .

Specifically, a sealing groove is disposed on the second housing 61 for placing the sealing ring 64. The operating wheel 211 of the adjusting unit 20 is provided with a supporting rib. The supporting rib is inserted into the sealing groove and is in contact with the sealing ring 64. When the operating wheel 211 is rotated, the friction between the adjusting unit 20 and the second housing 61 is reduced under the barrier of the sealing ring 64.

In the following, the strap 62 is included with the rack 621, and the adjusting unit 20 is rotated clockwise to take the strap 62 as an example. The method of using the adjustable strap 62 is described in detail as follows:

When the adjustable strap 62 is in the initial state, the limiting unit 10 and the adjusting unit 20 are in a connected state. At this time, the locking teeth 13 mesh with the locking teeth 23, and the adjusting unit 20 can only rotate clockwise, and the initial adjustment of the strap 62 can be adjusted. See Figure 6 for the status.

When the strap 62 needs to be tightened, the operating wheel 211 is rotated clockwise, and the operating wheel 211 drives the transmission gear 212 to rotate, so that the two straps 62 move in opposite directions, thereby tightening the strap 62; or

A compressive force is applied to the strap 62, and the strap 62 drives the transmission gear 212 to rotate clockwise. When the pressure disappears, under the action of the locking teeth 13 and the locking teeth 23, the strap 62 cannot be relaxed, and the current strap is locked. The tightness of 62;

The control unit 30 separates the limiting unit 10 from the adjusting unit 20 by an external force. At this time, the locking teeth 13 are separated from the locking teeth 23, the strap 62 can be freely stretched, and the operating wheel 211 can be rotated clockwise to tighten. After the external force disappears, the control unit 30 and the locking button 12 are returned to the initial position by the first compression spring 40 and the second compression spring 41, so that the locking teeth 13 mesh with the locking teeth 23, The strap 62 is unable to perform a relaxed operation, locking the current tightness of the strap 62.

When the locking teeth 13 and the locking teeth 23 are in the meshing state, the operating wheel 211 is rotated counterclockwise or a tensile force is applied to the strap 62, because the ratchet surface of the locking teeth 23 and the ratchet surface of the locking teeth 13 cooperate. The operation wheel 211 is prevented from rotating counterclockwise.

When the strap is required to be loosened, the control unit 30 separates the limiting unit 10 from the adjusting unit 20 by an external force. At this time, the strap 62 can be freely extended and contracted, and the transmission portion 21 of the control unit 30 can be rotated counterclockwise, or tied. The belt 62 applies a tensile force. When the tightness is adjusted, the external force applied to the control unit 30 is withdrawn, and the second compression spring 41 bounces and resets the control unit 30 while the first compression spring 40 bounces the locking button 12. The reset causes the locking teeth 23 to engage with the locking teeth 13, and the locking teeth 13 mesh with the locking teeth 23 to lock the tightness of the binding band.
